Appearing in Virginia Monday to support gubernatorial candidate Ken Cuccinelli, Paul expounded on the basis for his fear.

He addressed a crowd at Liberty University, saying that “much of your potential — or lack thereof — can be known simply by swabbing the inside of your cheek.”

Combined with America’s permissive attitude toward abortion, he said that such technological advances could usher in a renewed focus on weeding out undesirable members of society.

“Are we prepared to select out the imperfect among us?” he asked.

Though no empirical evidence shows that scientists are re-examining eugenics in earnest, a recent increase in interest regarding gender-selection abortions might pave the way for even more intrusive means of deciding who should have an opportunity to be born.

Cuccinelli also addressed his concern for the unborn, explaining that he has “been attacked rather vigorously for being a proud pro-life candidate for governor,” noting that an individual cannot “get any other rights to defend if you’re not born.”

The appearance was unsurprisingly denigrated by the left, for which abortion is a political sacrament. Democratic Party of Virginia spokesman Brian Coy attempted to portray the event as an effort to reach out to the extreme right wing of the GOP.

When the concern for the huge number of children whose lives are snuffed out in the womb is described as a partisan position, those rational Americans intent to remain a self-described moderate might want to reconsider their allegiance.
